Anyone else have very faint line on OPK test during predicted ovulation but no positive and still ovulate? I had this a few months ago, thought i hadn`t ovulated but a blood test confirmed i had, my CB ovulation never had a solid smiley face. Is this common? I have had positives in previous months but his month- nothing . I`m on Clomid 5-9, CD 17 and generally have A 32 day cycle.
